My element: Silicon (SI)

[1]


silicon_element.gif

No. of neutrons = 14
No. of Protons = 14
[2] Melting point 1414 degrees C

Most of the video is pretty boaring so only watch from 50 seconds to about a minute 35
(he is putting [silica gel, a form of silicon] in hot water)

History of silicon
[4] Around the year 1800 silicon was thought to be a compound
It was discovered to be an element by Jons Berzelius in 1823










Silicon and it's variations can be found in many places



[5] Silicon is a metalloid, the most common one on Earth and 2nd most common element in the Earths crust, also by weight. Silicon is the eighth most common element in the universe



===[6] Silicon can be found in space:

===
  • in stars
  • It is a main substance in a type of meteorite called aerolites
===





Silicon is found naturally on Earth




Silicon is very rarely found in nature on it's own, it is more often found as a compound or as a fault line in gold, sand, opal, rock crystals, amethyst, agate, flint, asbestos, feldspar, clay, mica and jasper or in volcanic rocks. It is most common though, in silicon dioxide aka quartz

Silicon facts that no one really cares about:







===
  • [7] Silicon is one of the few elements whose density is higher as a liquid than as a solid



    • Usually to create silicon for commercial use it is done by burning silica with wood, coal or charcoal at a temperature of 1900˚C +. The carbon reduces the silica to silicon and the liquid is drained and frozen into a solid.
    • In its pure form silicon is like glass in that it is strong brittle and gets chips if dropped although it is a grey-blue-silver colour.









  • Silicon is very usefull


  • [8] Silicon is one of the most widely used elements. Many minerals contain silicon, so anything made with sand, rock forms or clay (e.g. glass, bricks, ceramics and concrete), is made with silicon.[9] It is also useful in factories that work with high temperatures as it has a high melting point.
  • Hyperpure silicon ( silicon in it’s most pure form) is saving the planet, it is used in making solar panels.

  • some hair products even contain silicon t make you hair smooth, although it is actually bad for your hair making it suffocate.

  • [10] Silicone is a main component of rubber and can be found in many different of products, some of these include food preparation and storage products, a few kinds of clothing with elastic, shoes, electronic appliances, medical appliances and implants and glue like silicone sealer.
  • Silicon rubber works well in extreme environments of -55˚C - 300˚C and is not as susceptable to wear in sunshine

  • It is a semi-conductor which means it can conduct electricity or it can be an insulator depending on what condition it is in. That is it's most useful proporty, it has been harnesed to make the silicon chip or the I.C.
  • if you are interested in the silicon chip and don't mind some heavy reading click here to find out more integrated curcit wikipedia

  • · silicone can be electrically insulative or conductive, it is perfect for many electrical components
  • · Stability under intense temperatures of −55 to 300 °C).
  • · It is water resistant and so is good when being used for watertight seals
  • · It is resistant to many things that would wear down other materials such as sunlight and heat. Thus it is used often as piping, sealant or as a fire protector.
  • · It isn’t sticky which makes it easier to handle.
  • · It reacts with hardly anything unless you force it to in a man-made environment and is therefore safe to use with pretty much anything.
  • · It is nontoxic which makes it safe to us with food and other thing that are used in the mouth such as mouth guards and dummies (pacifiers).
  • · It can be made very greasy and is an excellent lubricant
